Abstract Background: Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. Objective: To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM) staging in oral cavity squamous cell carcinoma (OCSCC) patients and any impact of the same on survival. Materials and Methods: Retrospective chart review from year 2007 to 2013, at a tertiary care center. Statistical Analysis: All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA). Disease-free survival curves were generated using Kaplan-Meier algorithm. Results: One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2%) were males and 48 (37.8%) females with a mean age at presentation 43.6 years (29-79 years). The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Conclusion: Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.

Abstract Background A nomogram was developed to predict lymph node metastasis (LNM) for patients with early-stage esophageal squamous cell carcinoma (ESCC). Methods We used the clinical data of ESCC patients with pathological T1 stage disease who underwent surgery from January 2011 to June 2018 to develop a nomogram model. Multivariable logistic regression was used to confirm the risk factors for variable selection. The risk of LNM was stratified based on the nomogram model. The nomogram was validated by an independent cohort which included early ESCC patients underwent esophagectomy between July 2018 and December 2019. Results Of the 223 patients, 36 (16.1%) patients had LNM. The following three variables were confirmed as LNM risk factors and were included in the nomogram model: tumor differentiation (odds ratio [OR] = 3.776, 95% confidence interval [CI] 1.515–9.360, p = 0.004), depth of tumor invasion (OR = 3.124, 95% CI 1.146–8.511, p = 0.026), and tumor size (OR = 2.420, 95% CI 1.070–5.473, p = 0.034). The C-index was 0.810 (95% CI 0.742–0.895) in the derivation cohort (223 patients) and 0.830 (95% CI 0.763–0.902) in the validation cohort (80 patients). Conclusions A validated nomogram can predict the risk of LNM via risk stratification. It could be used to assist in the decision-making process to determine which patients should undergo esophagectomy and for which patients with a low risk of LNM, curative endoscopic resection would be sufficient.

e15548 Background: Around 90% of cancer-related mortalities are caused by tumor metastasis. CTC clusters, which constitute an intermediate stage of metastasis, have not been studied extensively in head & neck cancers. The mortality rate of oral cancers remains alarmingly high, despite multimodality treatment. The aim of the study is to identify the presence of CTC clusters in patients with Oral Squamous Cell Carcinoma (OSCC) and to correlate their presence with clinical and pathological factors. Methods: Fifty patients diagnosed with histologically proven OSCC, treatment naïve, and underwent surgery at HCG Cancer Centre, Bangalore, were consented and enrolled in the study. An IRB-approved protocol allowed for the collection of 10 ml of blood from central (jugular) and peripheral veins intra-operatively, prior to tumor removal. The culturing of CTC clusters was done using ellipsoidal microwell plates maintained at hypoxic conditions, at the Institute of Bioinformatics, Bangalore. After fourteen days of culturing, the cells were fixed and stained for DAPI, Pan-CK and CD45. The CTC clusters were classified into Loose, Tight and very Tight based on the median gray values obtained from DAPI staining on ImageJ software. Clinical data was collected from patient records and subjected to analysis using Descriptive statistics. Results: From the 50 patients included in the study, 22 (44%) patients exhibited tight clusters in central blood, while only 13 (26%) patients exhibited tight clusters in peripheral blood. A higher clinical stage was observed in a greater percentage of patients with tight clusters in central blood (early: 45.5% versus late: 54.5%), but the same findings could not be inferred with pathological staging (early stage: 59.1% versus late stage: 40.1%). No significant correlation with adverse pathological features was noted. Conclusions: This observational study provides an insight into the varying biological behaviours of similarly grouped cancers, which is based on the standard TNM staging. The study forms the basis for the hypothesis of tight clusters in the central and peripheral circulation, correlating with loco-regional and distant metastasis respectively, thus leading to poorer disease-free and overall survival rates.
